The Crown of Thorns at Notre Dame Cathedral in Paris. The relics of the Passion presented at Notre-Dame de Paris include a piece of the Cross along with the Holy Crown of Thorns, and of all the relics at the Notre Dame de Paris Cathedral, the Crown of Thorns is without a doubt the most precious and the most revered.
Once the Revolution was finished, the Crown was sent off to Notre Dame, where it remains to this day. So, what do we have in Notre Dame? Several branches, at least a 1000 years old, shorn of the thorns, stored in a glass case with gold and silver ornamentation.
